  • Publication number: 20030108013
    Abstract: A method and an apparatus for transmission power control of uplink dedicated physical channels in a CDMA communication system having channels for HSDPA. The method and apparatus enables a node B to reliably interpret an uplink control channel for HSDPA. The method and apparatus can simultaneously control powers of both a control channel for HSDPA and other control and data channels.

  • Publication number: 20030043764
    Abstract: There is provided a method for allocating channel numbers to channel signals by a Node B, which repeatedly transmits a stream of n channel signals to a UE (User Equipment), each of the channel signals including a channel number and transmission data, the n channel signals having (n+1) different channel numbers, each channel having a given transmission time interval (TTI). The method comprises storing channel numbers of the n channel signals in a transmission window, and updating channel numbers such that n channel numbers are stored each time channel signals are transmitted; and allocating the same channel number as a channel number used for initial transmission to a channel signal to be transmitted if the channel signal to be transmitted is a retransmission channel signal, and allocating a channel number not belonging to the transmission window among the (n+1) channel numbers to a channel signal to be transmitted if the channel signal to be transmitted is an initial-transmission channel signal.

  • Publication number: 20030039270
    Abstract: A signaling method between a MAC (Medium Access Control) layer entity of a transmission apparatus and a MAC layer entity of a reception apparatus in a packet communication system including the transmission apparatus and the reception apparatus wherein upon receiving a signaling request, the MAC layer entity of the transmission apparatus transmits a MAC signaling message including control information and a signaling indication indicating transmission of the control information and the MAC layer entity of the reception apparatus determines whether the MAC signaling message includes the signaling indication, and receives the control information included in the MAC signaling message, if the MAC signaling message includes the signaling indication.

  • Publication number: 20030031119
    Abstract: Transmitting user data in an HSDPA (High Speed Downlink Packet Access) mobile communication system by using an FCS (Fast Cell Selection) technique where an RNC (Radio Network Controller) transmits packet data only to a Node B that is best able to transmit data to a UE (User Equipment) on the downlink.

  • Publication number: 20030016698
    Abstract: A method for resetting a MAC-hs (Medium Access Control-high speed) layer entity in a communication system using HSDPA (High Speed Downlink Packet Access). When an RLC (Radio Link Control) layer entity is reset due to occurrence a protocol error, the system resets both a MAC-hs layer entity of the RLC layer entity and its counterpart RLC, thus preventing unnecessary data transmission.

  • Publication number: 20030007480
    Abstract: Disclosed is an apparatus and method for retransmitting data in a mobile communication system. A MAC-h (Medium Access Control-high speed) layer transmits, to an RLC (Radio Link Control) layer, received data and information on whether a retransmission process on errored data is being performed, thereby to prevent the RLC layer from performing duplicated retransmission on the errored data.

  • Publication number: 20030002472
    Abstract: A method for transmitting information in a mobile communication system using HSDPA (High Speed Downlink Packet Access) service. When an RNC (Radio Network Controller) generates or changes HSDPA service-related information, it transmits the generated or changed information to a Node B and a UE along with an indicator indicating the change in the HSDPA service information. Therefore, the Node B and the UE simultaneously operate by receiving the generated or changed information, resulting in an increase in the HSDPA service efficiency.

  • Publication number: 20020141367
    Abstract: A device and method for configuring an UL-DPCCH. One or more UL-DPCCHs, especially a UL-DPCCH for supporting HSDPA, are constructed in code division multiplexing and transmitted according to the characteristics of control information. The UL-DPCCH of the present invention that delivers various kinds of control information can be configured flexibly and operate in compatibility with a conventional asynchronous mobile communication system.

  • Publication number: 20020136193
    Abstract: Disclosed is a method for controlling uplink transmission power in a handover region by a UE in communication with a Node B using an FCS scheme. The UE stores TPC commands received for a specific duration from a plurality of cells in an active set, if the UE enters in the handover region during communication with a current best cell. If a next best cell is selected from the plurality of the cells, the UE determines a transmission power offset by comparing TPC commands from the current best cell with TPC commands from the next best cell for the specific duration at a time point where the best cell is changed from the current best cell to the next best cell. The UE transmits initial transmission power for the next best cell at a transmission power level determined considering the transmission power offset.

  • Publication number: 20020082020
    Abstract: The present invention relates to a system for gating a dedicated physical control channel in a mobile communication system. A UTRAN (UMTS Terrestrial Radio Access Network) transmits a gating start command or a gating end command to a UE (User Equipment) through a specific transport format combination indicator symbol according to whether there exists data transmitted over a downlink physical shared channel and a dedicated physical data channel, thereby to start or end gating the dedicated physical control channel.
